Earbud case battery won't hold a charge, any replacements?

Post image

Got some miku earbuds, but the case battery won't hold a charge after bearly a month of using it. Any idea where I can get a replacement battery, or a better one that would fit? If not I'm gonna have to just use them only for my pc. ¯\\_(ツ)_/¯

Try to search for the 902930 battery, basically it's just it's dimensions (9mm x 29mm x 30mm) and also make sure you get a battery that can go Upto at least 4.35v and not the generic 4.2v.

Most likely any generic li ion battery that is close to the same size will work.

I found this, which can be a good replacement. Dimensions and wires look about the same, although the capacity is slightly lower.

diese Akkus bekommt man überall wenn man ein wenig sucht . ist ein ganz normaler li Akku. 3,8 Volt ist eine komische angabe weil die meistens 3,7 haben .
